The Hot Aqua Blaster Hudson has an industrial, liquid-cooled Kubota diesel engine, which drives the Aquabar high-pressure pump directly via a close-coupled reduction gearbox.
The diesel engine is cooled by means of a heat exchanger. The washing water is pre-heated and then heated to the desired final temperature using a highly efficient high-pressure heating coil.
This Waterkracht Ecoboiler heating system can achieve fuel savings of up to 20%! The series is equipped as standard with a Waterkracht-Zero pressure regulation system, which ensures that if the high-pressure trigger is switched off, the pressure is turned off in the whole unit, from the trigger gun back to the high-pressure pump, so including the hose. When work resumes, the operating pressure of the system is restored immediately.
